Rhododendron catawbiense ‘Boursault’

Rhododendron catawbiense ‘Boursault’ (Rhododendron catawbiense ‘Boursault’). Rhododendron catawbiense ‘Boursault’, commonly known as ‘Boursault’ rhododendron, is an evergreen ornamental shrub with a broad, dense habit, recognized for its vigor and spectacular flowering. In spring, it produces generous clusters of lilac-purple flowers marked with darker shades at the center, creating a luminous effect in shaded beds. Its dark green, leathery, and glossy foliage remains attractive all year round and provides a solid winter structure. Very hardy and reliable, it adapts well to northern climates when planted in partial shade in acidic, organically rich, and well-drained soil.

To plant Rhododendron catawbiense ‘Boursault’, choose a suitable exposure: partial shade. The recommended soil is acidic, rich in organic matter, and well-drained. The soil should remain consistently moist without retaining water around the roots. Protect flower buds and foliage from drying winds. Avoid deep digging around the base and limit pruning to necessary interventions after observing regrowth. Water the root ball before planting and ensure water can drain after planting. During establishment, check moisture levels by hand before watering again.

Allow a width of 2 m (6.5 ft) when planning for this plant in your garden. The indicated height of 2 m (6.5 ft) helps determine its position relative to neighboring plants. Maintain access to the base for weeding, checking moisture, and removing damaged parts. Associate this variety with plants that have compatible light and water needs. If considering a container, first ensure its volume and drainage are suitable for root development. Roots in pots are more exposed to cold than those planted in the ground.
